may concern Be it known that I, OsoiinM. octetsa citizen ot' theUnitedlStates. and a resident of North Eindover, county Of ESSGX, Stateor lilassachusetts, have invented an Improve-Q ment in Machines forPicking and Burring W0o'l,;Etc., of wlnch the following descrlp tion;inv connection with the accompanying drawing, is specifi.cation,'.likecharacters.

on the drawing representing like parts:

This invent on relates to a machine for pic-king and burring'wool' andsimilar fibres acting to straighten out the; fibres and re- 'IHOVGtherefrom the dirt, burrs and foreign substances associated therew1th.

The object of the invention is to provide an improved means for insuringthe renoval'of the burrs and preventing waste of fibres I The object ofthe invention is more particularly to provide in combination. with sucha machine a ro'taryfbrush and guard plate so positioned and arranged asto re.- pass through the curring operation burrs knocked out andcarrying fibre.

These and other objects and featuresof the invention will appear morefully'froni the accompanying description and drawings and will bepartlcularly-pointed out in the claims. v p i In the drawings; Figure 1illustrates diagrammatically in general side elevation afainiliar' typeof picking and burring machine having embodied therein a preferred formofthepres-v ent. invention Figure 2 is a side elevation partially inlatesto but one, although an important step.

or feature of the b urring operation it is necessary only to illustrateand describe in detail those parts of the: machine particu larlyconcerned with the present invention. Figure 1. shows the entire machinein adiagrainrnatie form and itwillbe'recognized by those'skillecl inltheart as of affaniiliair type. Such a "r achine in general comp-rises afranie and casingl en. losing all theworking parts. At theadinission'end ofthe machines endless conveyor2 is inountedland driven.The niass'offivool or oth r fibre'is deposited on this conveyorandcarried thereby intothe bite of a. pair of feed and separatingroIlsB.The fibre is takenlironi these:

[ olls by themain beat-er cylinder revolving I on the shaft et nside ofa cylindrical cage This beater cylinder usually coinprises' spider-likeheads 5, partially shown indetail in Fig. 2,.and on the.pe-riphery'ofthese heads areusually n ounted parallel spaced slats 6carrying rows of teeth '1 pro ecting in the direction of rotationindicated by the arrows. These teeth seize the mass of fibre.

from the rolls3. During therot-ation o f'the' beater cylinder theheavier dirt and foreign substances drop between the slats into the cageand fall out at the bOttODIWhllethe lighter dirt and dust are. suckedout from the cage a suction top of the casing. y y f At the side oftl febeatercylin der opposite thet'eed is' nounted a rotary burring cylinder9 This cylinder rota es in a CllIQCtlOaIl opposite to that of the mainbeater cylinder and is provided onits exterior with rowsof teeth 10pointing in the directionof' rotation of the burrin'g cylinder andgenerally formed in the periphery of parallel annular steel bladesspaced throughout the length 0t the cylinder. Theperiphery of thisburring cylinder is sufiiciently closeto the path travelled by theteeth-7 of the main beater cylinder to cause the fibres to be taken bythe burring' cylinder from the main beater cylinder and to lie in abaton theperiphcral sur face of the burring cylinder. i v

A rot-aryburr guard 11 is mounted peripherally adjacent and usuallybeneatl1,the

V burringcylinderQ. This burr guard is'p-ro vided on its peripherywithuradially pro- 9; steel blades 12. The burr guard rojectin tates ata high speed and in the opposite di- I rectionto theb-urring cylinder.Its funcfan 8 mounted the p i tion to, knock off the' burrs and foreignsubstances lying on the periphery" of the burring cylinder While the fbres remain held in the teeth of the burr ng cylinder.

justahle the The burr guard in hearingblot cylinder and dischargedironi'the machine usually b a rotarv-brushlzi revolvin in a r they are to beunderstood as indicatingthe' direction opposite to that of thelasthurring Lylinder. 7 I Z hen the burrs are knocked out from the hat offibre by the burr guards, and particu- .larly in the case of the burrguard such as 11 first acting uponthe fibrefthey frequently carry withthem more or less fibre which is wasted or requires a separate operationfor its removal. The present invention acts to permit. such burrs itfree from fibre, to drop out of the machine but, if carrying fibre, actsto repass them through the hurringg op eration so as insure the saving;of this fibre.

While the invention may be applied to any or all or". the pairs ofcooperating burring cylinders and burr guards it is especial'lyuseful'in connectlon with the burring cylinder and burr guard firstacting upon the fibre after it passes from the main beater cylinder andit is consequently illustrated in the preferred form in thisbosition.While terms such as upper and lower and similar terms are herein usedfor convenience relationship the elements and not as re strictive.

In the preferred ei'nbodiment of the inven-i tion a cylindrical. rotarybrush 16 is mount- 7 7 ed in the angle between the main beater cylhinderand the burring cylinder 9.

v n V This brush is preferably formed as illustrated of tufts ofbristles so that its periphery presents substantially continuous surfaceof bristle points. The peri 'ihery ot this brush 1s so positioned-that131$ sufiiciently ad acent to the toothed periphery of the burn mgcylinder 9 as to press the fibres between i the, teeth of thel'iurringcylinder leaving, the

burrs and foreign substances on the surface.

The periphery of the brush is alsoso positioned that the teeth 7 of themain beater cyl nder in their travel past the brush may se ze burrscarrying fibre and held on the ,sur'tace o't the brush. The perish rv ofthis brush rotates at a slowe" the same direction as f teothed peripheryof the bllI'IlDQ cylinder.

'mountedjat its ends 1 is transterred from the bnrring cylin-' n thefinal burrin'g" d than out in The position oftherotary brushlG to securethe desired results is preferably sea cured by making the bearingscarrying the shaft 1.? of the brush adjustable in two directions hereinshown astirst in a direction radially of the beater cylinder and sec ndin a direction transversely of the plane of the radial adjustment: sothat as a result the brush is adjustable toward and from the peripheriesof both the main beater cylinder and the burring' cylinder. Theadjustment of one of the bearing blocks 4 J2 h' 3 1 q i8 ior the shaitLt shown in Figure 0.

The bearing block l8'is there shown moruu' ed on a bracket ls liiy meansof a bolt passing through a vertical slot in the t-el te 'caljarnrqtofthe bracket. *T he opposite cm} of the block 18 is provided with a sets rew 22 threaded therethrough and abuttinrfa surface 23 on'thetrame 1.tThus by loosenmg the bolt and adjusting the set screw ZZthebea'ringblock may he raised and lOVF ered with' respect to I the surface 23.This surface is shown as extending radially of the main ,heatercylinderand the bracket 19 together with tie lower end of the set screw22isslidable along this surface to give the desired radial adjustment.As a means for effecting the radial adjustment a set screw 2e is shownthreaded into the bracket 19 and: journalled in a bracket 25 secured bya' b olt 26 to the frame.

It willnow be seen that the burr guard ll.

is mounted the angle of diverging travel between the burring cylinder 9and tlie'brush 16 with its peripheryrot-ating 1n the opposite directionto the burring cylinder, but

as the periphery of through slots in the trains and the bases 28 arehorizontally adiustable on the brackets by means of .bolts 31passingthrough slots inthe brackets Thus the uart plate is adjustable tovary the distance between its upper edge and the periphery of thebarring cylinder and to vary the space between its bottom portion andthe hrush periphery.

An auxiliary guard plate 32 is mounted beneath the brush spa ed from the'main guard plate and is vertically adjustable toward and from the brushby means of the setscrew passing through a slot therein and into theframe.

Thebrushand the guard plates are so positioned, by means of theadjustments provided, that the burrs knocked off vfrom the iii 1 ron-27iibrc on the ljlll'flfll'lf cylinder by the burr "d ll are thrown overthe topjotthe plate 27; and against the brush 16. at are tree from fibreslide down the curved surface otthe guardiplate 'Q'UfllCl plate isadjusted closer;

and drop out through the-bottom or through the opening; provided b weenthe main guard plate and thc auxiliary guardgplate 39, burrs that stillcarry fibre-clinginose ing to them are caught'by the brush and, the

'usln are rolled around by the-lbrush and n nany cases the fibre isstripped'from hem brthc brushaiso'that they'are freed from fibre anddrop outat the bottom! 'ihos ct fibre still cling to the brush and arecarried around and repassed through the burroperation. With thebrushlocated in the position shown in Fig. 2 such burrs and ibre areseized by the teeth of the main beater cylinder and carried around andtransferred to the burring cylinder to go through the operationagainjThus it is practically impossible for burrs to pass through the machineand be discharged therefrom carrying fibre and it is practically insuredthat the fibre shall be stripped or removed from the burrs.

The adjustment or" the upper edge of the guard plate 27 toward and fromtheperiphery' of the burning cylinder depends upon the'lnnd of thestocklbeing acted upon. If the stock is light the guard plate may beadjusted'further away to prevent the fibre being carried down to theright of the guard while if the stock is heavy the The burr guard actslike a fan and if thejstock were too light the fibre would carry down tothe right of the guard-which would obviously be obgectio'nable.

The brush as has been pointed-cutie preferably made of bristlessoinserted as to glve a continuous surface containmg a very large numberof pointed ends per-square inch, a

much larger number thanris yet commercial in a wirebrush, but theinvention is not'to be restricted to the particular kind of brush solong as it performs the desired function.
